coking coal required for production of coke which is used in steel industries and non coking coal required for thermal power plants for steam production. coking coal required for production of coke which is used in steel industries and non coking coal required for thermal power plants for steam production.
Bharat Coking Coal Limited was created in 1972.
Coke is made by heating coal in the absence of oxygen to about 2000 degrees Fahrenheit. Hard coking coal forms high-strength coke, while soft coking coal produces a lesser quality coke.

Coals as straight or in blend which on carbonization produce hard coke are known as coking coals. Depending upon coking capacity, coking coals are divided into prime or hard coking coal, medium or soft coking coals and weakly or semi-soft coking coals. The coking coals are classified based on CSN, LTGK coke type, gieseler fluidity, vitrinite contents, mean maximum reflectace of vitrinite etc. On the other hand, coals which on carbonization produce powery mass are known as non-coking coals. Coals having CSN 0-1 and LTGK coke type of A and B are non coking coals. Dr. Tamal Kanti Das DGM, RDCIS, SAIL, Ranchi, India
Strongly caking coals, which yield a solid product (coke) with properties suitable for use in a blast furnace, are called coking coals. All coking coals are caking, but not all caking coals are suitable for coke making.
No the coal will turn in to ashes and it is made to make long lasting fires.
